BLIL PFC Boost Converter for Plug in Hybrid Electric Vehicle Battery Charger

Vyshakh. A. P; Unni. M. R

Abstract: AC-DC Converters are the key component in the battery chargers of PHEV (Plug-in Hybrid Electric Vehicles). Most commonly used AC-DC PFC (Power Factor Correction) topologies in PEHV battery chargers are conventional PFC boost converter, bridgeless PFC boost converter and interleaved PFC boost converter. To overcome the disadvantages of the above mentioned topologies bridgeless interleaved (BLIL) PFC boost converter was developed. The conventional PFC boost converter and bridgeless interleaved PFC Boost topology were designed and simulated using MATLAB/SIMULINK. Conventional PFC Boost Converter was designed for interval D=0.6 and bridgeless interleaved topology were designed for two duty intervals D>0.5 and D<0.5.The input performance parameters such as THD (Total Harmonic Distortion) and power factor for the two topologies were obtained and comparison were made between the two topologies. The input supply voltage used for both the converters are 230V.
